FA551X series
CMOS IC
For Switching Power SupplyFCAo5n5tr1oXl
FA5510P (N), FA5511P (N)
FA5514P (N), FA5515P (N)
■ Description
The FA551X series are the PWM type switching power supply
control ICs that can directly drive power MOSFET. These ICs
use a CMOS device with high dielectric strength (30V) to
implement low power consumption. These ICs contain many
function in a small 8-pin package. With these ICs, a high-
performance and compact power supply can be created
because not many external discrete components are needed.
■ Features
• Low current consumption by CMOS process with high
dielectric strength (30V)
• Standby current of 2µA or less (at Vcc=14V), and operating
current of 1.5mA (typ)
• Overvoltage protection function detecting the Vcc voltage
• A drive circuit for connecting a power MOSFET directly
• Output peak current: ±1.5A
• Pulse-by-pulse overcurrent limiting function
• Overload protection function (latch or non-latch mode selectable)
• Output ON-OFF function by external signal
• Latch-mode overvoltage shutdown function
• Undervoltage lockout function (16.5V ON / 9V OFF)
• Reference voltage output (5V)
• 8-pin package (DIP/SOP)
